1.Structure of  Ball Valve Description

Threaded ball valve is closed is a ball, ball around the center line of the body as a rotation to achieve a kind of open and close the valve.
Ball valve in the line is mainly used for cutting, distribution, and change the flow direction of medium. Two type ball valve, three type ball valve, is widely used in recent years a new type of valve, the valve average installation. And ball valve is a kind of ball valves, threaded pipe connection is screwed connection, and flanged ball valves, welded ball valve, etc.

2. Main Features of the Ball Valve

• Small flow resistance;

•  Simple structure

• Small volume, light weigh

• Small volume, light weigh

•  Easy to operate, open and close quickly, facilitate remote contro

• Easy maintenance, sealing ring, which generally remove easy to change

• Full open or full close, sphere and valve seat sealing surface and the dielectric isolation, medium through does not cause the valve sealing surface erosion.

4.FAQ

1. What's are the characteristics of ball valve?

The distinct feature of a ball valve is the sealing surfaces between the gate and seats are planar, so ball valves are often used when a straight-line flow of fluid and minimum restriction is desired. The ball valve faces can form a wedge shape or they can be parallel. 

2. What is the work principle of ball valve

 The ball valve faces can form a wedge shape or they can be parallel. Ball valves are primarily used to permit or prevent the flow of liquids, but typical ball valves shouldn't be used for regulating flow, unless they are specifically designed for that purpose. Because of their ability to cut through liquids, ball valves are often used in the petroleum industry. 

3.  What is the structure?

Bonnets provide leakproof closure for the valve body. Ball valves may have a screw-in, union, or bolted bonnet. Screw-in bonnet is the simplest, offering a durable, pressure-tight seal. Union bonnet is suitable for applications requiring frequent inspection and cleaning. It also gives the body added strength. Bolted bonnet is used for larger valves and higher pressure applications.

Q:Pump, valve, these belong to the material?
In the stainless steel industry category: sheet only belongs to the material! In the mechanical and electrical equipment categories: valves in the screws, gaskets, nuts are materials! This is relative!
Q:What does the "XV" valve mean?
XV:X said V is plug valve, said valve body material is chrome molybdenum vanadium steel.
Q:Valve category can fill the trunk door, branch valve Mody?
Valve category refers to the type of valve, the big species are divided into: butterfly valve, gate valve, globe valve, ball valve, check valve, control valve, trap and electric valve,
Q:What is the difference between a stop valve (a power station valve) and other valves?
High pressure, special material, complex structure, seldom manual operation.
Q:What is the valve?
The definition of a valve "valve" is defined in the fluid system, used to control the direction of the fluid, pressure, flow device. A valve is a device that flows or stops the medium (liquid, gas, powder) in a pipe and equipment and controls its flow. Valve is the control component of pipeline fluid transportation system. It is used to change the passage section and medium flow direction, and has the functions of diversion, cut-off, adjustment, throttling, check, diversion or overflow, pressure relief, etc.. For fluid control valves, valve from the simplest to the most various valves automatic control system used in complex, its many varieties and specifications, the valve nominal diameter from industrial piping and instrumentation valves tiny tolarge diameter 10m valve. The valve can be used for the control of water, steam, oil, gas, mud, all kinds of corrosive medium, liquid metal and radioactive fluid and other types of fluid flow, the valve working pressure from 0.0013MPa to 1000MPa ultra high pressure, working temperature from ultra low temperature to high temperature of 1430 DEG -269. Control valve can be a variety of transmission methods, such as manual, electric, hydraulic, pneumatic, worm gear, electromagnetic dynamic, electromagnetic hydraulic, electric hydraulic, pneumatic and hydraulic, gear, bevel gear drive; in pressure, temperature or other forms of sensor signals under the action according to the requirements. Or do not rely on a simple sensor signals to open or close the valve on the drive or automatic mechanism to make the opening and closing parts for lifting, sliding, rotating or turning motion, thus changing the size of the flow area to achieve its control function.
Q:How do you calculate the pressure difference between the front and rear of the valve?
The valve according to feature points, can be divided into isolation, cut off, check, overflow and regulation, which belongs to the regulation is more complex, such as for a compressible medium, constant flow regulating valve after the pressure is more and more big, natural gas pipelines are now part of the regulating valve the self,
Q:What does the torque of the valve mean?
The opening moment (torque) is the force or torque that must be applied when the valve is opened or closed. Need to open and close the valve when the sealing pressure than the formation of closed and valve seat sealing surface between the two, but also to overcome between the stem and the packing between screw stem and the nut, the valve stem friction end bearing and other friction parts. Therefore, certain closing force and closing torque must be applied, and the required opening and closing force and opening and closing torque during the valve opening process are varied, in which the maximum value is at the closing instant or the initial opening moment. Design and manufacture of valves, should strive to reduce the opening and closing force and opening and closing torque.The open torque can be obtained by means of calculation or measurement, and can be obtained by hand torque measurement.
Q:Can the angle valve of York central air conditioner be replaced by other valves?
Definitely. But I want you to tell me what you're doing, or give me a picture. I can give you some advice
Q:What's the caliber of the valve 1/4?
1 inches, =25.4 millimeters, 1/4 inches, =2/8 inches, =2 minutes, =DN8 (mm)3/8 inches =3 points =DN10 (mm)1/2 inches, =4/8 inches, =4 minutes, =DN15 (mm)3/4 inches, =6/8 inches, =6 minutes, =DN20 (mm)1 inches =DN25 (mm)1 1/4 inch =DN32 (mm)1 1/2 inch =DN40 (mm)2 inches =DN50 (mm)
Q:How many valve enterprises in China's valve industry?
Chinese valve is mainly produced in Zhejiang, where Wenzhou, Shanghai there are a lot of Zhejiang valve in Wenzhou, but also Shanghai valve production, many are also Zhejiang boss, the key depends on whether you need what valve valve, the valve may be located in different regions is not the same
